| Research Abstract |
After the revision of the law, certain amounts of uncontained radio isotopes (RI) became available for student practice at junior high and/or high schools. In this study, we developed several teaching materials and teaching methods using RI for student practices, e.g., determination of genetic substance, verification of the central dogma theory, verification of rules of base composition in DNA, relationship between atomic number of shielding materials and transparency of gamma ray, relationship between distance from RI and effective dosage, determination of radioactivity of cesium in soil. We evaluated performance of inexpensive radiation detectors for the usage in these schools.
